Restrictions for Donating Blood as Stated by the American Red Cross It is said that 70% of Americans are eligible to give blood even though the criteria to donate seems quite strict. Each case is treated individually based on why the person is donating. An autologous donor is one who is giving blood to use for them self if needed during a future surgery. All others are anonymous donors who donate blood for others to use when it is needed. I will discuss the reasons why a person could not donate blood as an anonymous donor in this essay. Some things such as age and weight have minimum limits but not maximum limits. A person must be at least 17 years old in most states to donate their blood; this is because a person is generally considered an adult at the age of 17 and does not need parental consent to donate. The Minimum weight limit is 110lbs. The reason for this requirement is to protect the donor. A person under 110lbs may not tolerate having a pint of their blood removed because of how little they had to start with.

but that does not always mean one cannot donate blood. If a person were on the following medications, they would never be allowed to donate their blood: Tegison, a human pituitary-derived growth hormone, Coumadin, or Heparin. Other medications such as Plavix, Accutane, Soriatane, and Avodart require that the donor wait to donate blood for 3 days to 3...

...“Americans were still professing their loyalty to George III and their desire for peaceful reconciliation as late as 1775. Had Britain accepted the Second Continental Congress’s Olive Branch Petition, the Revolutionary War could have been avoided.” Support or refute this claim using historical evidence.
Even though delegates at the Second Continental Congress sent the Olive Branch Petition to George III requesting reconciliation, the recent skirmishes and hostile American public opinion made peaceful resolution unlikely, if not impossible. The delegates of the Continental Congress appeared aware of this inevitability themselves, for at the same time that they wrote their final petition to George III, they also made defensive provisions for a navy and an army, the latter to be commanded by George Washington. Moreover, even if the delegates truly believed that peaceful reconciliation was possible, it is doubtful the American public shared this belief. The Committees of Correspondence had by 1775 become powerful distributors of anti-British propaganda to both city dwellers and rural settlers alike.In addition, the organization and rallying that enabled the boycott on all British goods turned many colonists into patriotic Americans. This desire for independence was confirmed at the Battle of Lexington and Concord and the Battle of Bunker Hill, in which simple farmers refused to retreat from the powerful British army and instead stood their ground. Thus, even though...

Use mosquito repellent sprays, and add appropriate insecticides, such as larvacide, to water containers to prevent mosquitoes from breeding.
Additionally, make sure that your drains are always clean to ensure that they are not blocked, especially during the rainy season.
If you notice fogging being done in your neighbourhood, you can be sure there has been a case of dengue among your neighbours.
Be extra vigilant and clear your garden of breeding areas, and get tested if any family member has a fever.
The insects will fly into your house if fogging is done on the outside only.
Because these mosquitoes like to bite humans during the day, protect yourself by using a mosquito repellent on your skin while out gardening or on evening walks.
Wear loose and light-coloured clothes as mosquitoes find it hard to bite through loose clothes. Mosquito nets help too, even though the Aedesmosquito feeds during the day.
Prevention against the bite of an Aedes mosquito is extremely important, so that we don’t become human carriers, and multipliers of the virus by serving as the source of the virus for uninfected mosquitoes.
While awaiting the development of dengue vaccines, be vigilant in combating the spread of Aedes mosquitoes in order to save your loved ones...

...Identifying Biological Macromolecules in Food Lab.
Biochemists have developed standard tests to determine the presence of the most abundant macromolecules made by cells: carbohydrates (sugars, starches), lipids (fats), and proteins. In this investigation, your group will conduct some of these standard tests to identify the presence of sugar, starch, lipid, and protein in known samples. You will then use the same tests to analyze different food samples for the presence of these macromolecules. The class test results of various foods will then be combined and analyzed.
Pre-Lab Questions:
1. Why are you required to wear safety eyewear and protective clothing while conducting this investigation?
2. Why must the test tubes be thoroughly cleaned and dried when one part of the procedure is completed, before starting the next part of the procedure?
3. What colours indicate a positive test and a negative test for proteins, sugar and starch for the indicators used in this investigation?
4. What is Albumin? What is pepsin?
Question:
What biochemical molecules are present in different food samples?
Materials
* distilled water

A Prayer For Owen Meany
The Novel “A Prayer For Owen Meany” By John Irving is an inspiring story that follows two boys who live in the same town, one being a small and often diminished boy, Owen Meany and the other Johnny Wheelwright who loses his mother early in his life. It is narrated by Johnny himself, in which he describes how Owen altered his fate in god. The whole affair begins during a little league baseball game, when Owen hits a foul ball that unfortunately strikes Johnny’s Mom in the head, in turn killing her. After this event Johnny lives in different homes, however he and Owen remain good friends and together overcome many obstacles throughout their lives. Johnny tells his story to show the reader how powerful it can be to have a friend who is so inspirational and well guided, to promote his fate in god, and to show how magnificent of a person Owen Meany is.
A Reason for Johnny narrating the story is that even thought Owen kills his mother, his only link to knowing who his father is, he still manages to remain friends with Meany. This shows how much trust and admiration Johnny has for Owen. Throughout the novel, Owen continues to baffle Johnny with his “God Given” knowledge. Each time Owen assists Johnny; it makes Johnny want to become closer to god as he feels his friend is blessed. For example Johnny does not wish to join the army during the Vietnam war, and Meany ensures this wont happen as he convinces Johnny that cutting of his finger will exempt...

...attract people to agree with her statement bypointing out this view.Other fallacy is hasty generalization (stereotype version) such as in theninth paragraph, she claimed that Malaysians has been known to read the less.This assumption is not enough to conclude that all Malaysians read least becausethere are some of Malaysians are read most. Thus, this is a stereotype since theauthor convinced the readers that someone who has particular characteristics arebelongs to the group that has the same characteristic.Overall, this article is valid and credible since the author able to give thelogical reasoning to support his argument. The author has shown an ability todescribe and summarize texts but does not demonstrate good reasoning skills.

In my opinion, PPSMI policy should be continued because it used Englishlanguage as the medium of instructions between the teachers and students. AsEnglish language is the global lingua franca, so it became very importantespecially to increase the global understanding like to promote national security,and world peace. For example, English can be used to communicate the messagethat Islam is a religion of peace.
With good English, these misunderstanding ordisagreement can be resolved without bloodshed.Next, PPSMI policy is a very useful tool to teach the children Englishlanguage at the early age because they are ready to store up the new knowledgeas their mind still free from notions.

...so I would like to live in a house next to the beach, where I can see the sea from the windows, hear the sound of water, enjoy a warm weather and walk on the sand every morning. If the house had a garden I would sow a lot of pine trees because on the one hand they have sweet-smelling and on the other hand they are evergreen trees which keep nice throughout the year. I would enjoy reading and listening to music if I sat in a comfortable swing under the shadow of the trees where also I would sit during the summer nights.
My ideal house would be minimalist, without too ornaments and painted in white but with a well-equipped kitchen to try cook better every day.
I wouldn’t like to live in an enormous and sumptuous house where you can lose in it, I only want a comfortable, clean and family house, which smell freshly washed clothes and where I feel happy.
The house of my dreams.
Well, I’m no very strict with the house. I think I would be able to live in whatever kind of flat or house. Now a days I’m well in mine. But if I were a filthy rich man, I would look for a place which were near the sea and the mountains. I love both of them, so I would like to have a house which were in the mountains, but that I could see the beach trough the windows. It would be great.
The house should have two floors. In the...
